Abstract

Due to the strict regulations imposed on non-biodegradable mineral oil-based lubricants, the development and applications of biolubricants are increasing daily. Plant oils are being investigated as a potential source of environmentally favorable lubricants because of their biodegradability, renewability, viscosity-temperature relationship, low volatility and excellent lubrication performance. However, the use of plant oils has some restriction, the most critical being oxidative stability and low-temperature problems. This paper presents systematic modifications to improve the physicochemical and tribological properties of plant oil derivatives. The results showed that among the oleic acid-based triester compounds, 2-ethylhexyl 9-(myristoxy)-10-(heptanoyloxy)octadecanoate (9) had the lowest pour point (-47.19 °C) while 2-ethylhexyl 9-(caprooxy)-10-(heptanoyloxy)octadecanoate (5) had the highest onset temperature (103.10 °C). Overall, the data indicate that the biolubricant basestocks based on this chemical modification offer great potential for the development of industrial products application.
